MEASURlNG-VESSEL FOR LIQUIDS SPECIFICATION forming part of Letters Patent No. 406,366, dated July 2, 1889.

Application filed April 25, 1889. Serial No. 808,540- (No model.) Patented in Germany August 15, 1887, No. 45,332.

To all whom it may concern.-

Be it kn own that I, JOHN P. MULLER, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented. new and useful Improvements in Measuring Device for Liquids, (patented in Germany by Letters Patent, No. 45,332, of August 15, 1887,) of which the following is a specification.

This invention relates to a device for measuring liquids of the kind which serve for drawing the liquid in definite quantities from a vessel.

The peculiar features constituting the invention are set forth in the following specification and claims, and illustrated in the. ac-

companying drawings, in which Figure 1 is a vertical section of a measuring device along line x as, Fig. 2. Fig 2 is a horizontal sectionalong line 3 y, Fig. 1. Fig. 3 is Fig. 4 is a front View of a cock. Fig. 5 is a vertical section of a cock along line 00 00, Fig. 4. Fig. 6 is. a transverse section of a cock, so adjusted as to open the outflow. Fig. 7 is aview similar to Fig. 6, showing the cock in different adjustment than in Fig. 6.

Similar letters indicate corresponding parts.

The letter A indicates a chamber from which the liquid flows into the measuringvessel B. A cock 0 is secured to the vessel B,.and the shell or housing D of the cock has a series of openings cl d d (1 which lie within the vessel B. The cock is provided with the usual outflow E. The plug F of the cock sits in the shell D and has a depression f of such size that when the plug closes the outflow E the openings d d d d are in connection with the depression f, so that there is free communication between the interior of the shell of the cock and the interior of-vessel B. The liquid flows out of the chamber A through a tube S into the measuring-vessel B. The tube S communicates with the opening (Z in the shell D, so that the liquid flowing from chamber A through tube S can pass through openings d cl d d into the vessel B. From the opening (1' in the shell D extends a tube '1, which bends over so as to form a siphon. Another siphon I communicates with the opening (1 and the siphon I communicates with the opening d The mouths of the shorter siphonlegs are placed at different heightsin thevessel B, so that as the liquid is allowed to flow off through one siphon or another a greater or less quantity of liquid is drawn from vessel B. The short legs 1' i 2' of the siphons com municate with cups J J J 2 secured to arms j, having screw-threads for the reception of the screws K, theheads 7c of which extend through the bottom of the vessel B. By turning the screw K the cups are raised or lowered, the arm j swinging about suitable joints or pivots j. Suitable stuffing-boxes L prevent leakage at the screw-heads k. The liquid flowing out of the vessel B through a siphon will flow from the vessel until it reaches the cup of said siphon, when the liquid will flow from the cup until the liquid is below the siphon mouth in said cup, when the flow of liquid through said siphon stops. By adjusting said cup by its screw K the quantity of liquid drawn through said siphon can be accurately regulated.

In Fig. 1 the plug Fis in such position that the liquid will flow from vesselB only through siphon 1 If the plug F is turnedto the position shown in Fig. 7, the siphon I is brought into communication with the outflow E and more liquid is drawn from the vessel B. WVhen the plug F is turned to the position shown in Fig. 6, so that the siphon I communicates with the outflow E, more liquid is drawn from the vessel B. An index M, turning with plug F, can be made to indicate the quantity of liquid to be drawn. When the plug F is turned, so as to close the outflow E and open the apertures d d (1 (1 the liquid from chamber A flows through pipe S and through the siphons I I I and fills the vessel B and sightglass N. After filling the vessel B the liquid rises through opening 0 into chamber P, whence it passes to chamber Q, and, raising the float R, closes the valve T and prevents the further escape of air from chamber Q, thus arresting the inflow of liquid through pipe S. The chamber P communicates with the sight-glass N and chamber Q. The chamber A is kept supplied with liquid by means of a suitable pipe U. Excessive motion of the plug F is prevented by a pin h striking against suitable shoulders 72/, and a handle g can be used for actuating the plug.

1 do not herein broadly claim the combination, with a measuring-vessel, of a cup adjustably secured within said vessel and a siphon discharge-pipe connnunicating with said cup, nor a cock forputting the dischargepipe of the cup into communication with the feed-pipe and outlet of the measuring-vessel, such being embraced in an application filed by me April 7, 1889, No. 306,215.

hat I claim as new, and desire to secure to by Letters Patent, is

1. The combination, with the measuringvessel B, having a shell D, provided with a series of openings leading to the vessel, of an outflow E, a supply-pipe S, made to communicate with one of said openings, a series of siphons of varying heights made to communicate with said openings, adjustable cups into which said siphons dip, and a plug F, provided with a depression for opening and closing said openings, substantially as described.

2. The combination, with a vessel having a siphon, of a cup int-o which said siphon dips, a jointed arm holding the cup, and an adjusting-rod K for said arm, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN P. MULLER.
